I've been looking for something to wirelessly charge my Note 9 with the Samsung Rugged Case. This does that flawlessly. No more messing with wires while I drive. The bottom extends further down so that coils line up and the current is strong. I get a solid fast charge.The mechanism that's holds it in place seems solid too. Not quite as solid as the iOttie I was using but it seems more than sufficient. My big heavy phone doesn't move around while I'm driving.There is just one thing I don't like from a design perspective and that is how it grips and ungrips your phone. Generally you drop the phone in the cradle before or after you start the car and it grips the phone automatically. HOWEVER there is a little button to release the phone on the back and if it even senses a finger nearby it opens. My phone has fallen out as a result of this a couple times in the first 24 hours. I can get around this by simply interacting with the phone differently but felt it was worth noting. The other issue I have with the gripping mechanism is that if the phone is still gripped when I turn the car off, there is no power to release the grip. Again, I'll just have to change my behavior. Is it worth making these changes? I say yes. The rest just works so well.One other negative that turned into a positive to me is that I paid for a new unit but the one I received had been very obviously used. The box was torn and it had finger prints all over it. I got in touch with the seller and they got back to me and made it right in less than 24 hours. Without going into specifics their solution was much more than fair. Great customer service which you can really tell they stand by.*******5/19/19 Update*********After just a couple weeks of use this thing has started to get annoying, to the point that I may look for another option. It still charges great which was my main selling point but there are some other things to consider. First as mentioned in my original review the sensors that open and close the arms are really annoying. I've gotten better about not triggering them while driving but if I leave the phone in the holder and turn the ignition off, they phone is stuck. You have to turn the ignition on to release. If I'm just stepping out of the car quickly (which I do a lot) I sometimes choose to leave the phone in place. When I start the car again the arms open automatically and my $1000 phone crashes on my console and floor.The other annoying thing is the actually mount. The suction cup can't handle any kind of direct sunlight. The adhesive just turns right to goo. Never had a problem with my iOttie. The plastic seems to be of lower quality as well. I need to tighten it almost every other day and it feels like the threads may be starting to see strip.*********6/6/19 Update**********Once again, outstanding customer service. After my last update the seller contacted me and offered to send me a new upgraded version. It came a few days later. The charger portion looked a bit different but the mounting arm looked the same. Day one with my car parked out of the shade and I found the mount on the floor. I'm happy to say though that it has not fallen off since.Once again the charge works flawlessly.The location and sensitivity of the open/close buttons is still killing me though. If I could deactivate the right button I'd be great! Again the problem is that I have a Note 9. It's a big phone and to accurately push a button like selecting an app or music track, you have to sort of cradle the phone and use your thumb. When you cradle the phone ever so slightly the damn thing opens and drops your phone on the floor. I'm half considering taking this apart and disconnecting the right button since they seem to work independently.What is also fixed is that it no longer opens when I turn the ignition. This has been a HUGE improvement for me.Finally my other criticism was with the mounting arm itself. It kept loosening on the last mount and this one might be worse. On the first day it was rock solid. Second day I had to tighten it. What I'm left with now is that I can't tighten the one screw any further but yet the arms extends freely. It's not a super huge deal but again, heavy phone, so I got a bump and it's in another position. Tonight I put some silicone glue on to hold it in place and am fairly confident that will resolve the issue. My theory is that a lower grade of plastic was used for the mounting arm and as a result it is very reactive to temperature fluctuations.The seller has reached out a couple times so I wanted to update my review. The customer service is exceptional so I think you can buy with confidence that they want to sell you a good product. I still recommend it because I honestly haven't found a better charger out there. The main component is of very high quality, I just think that it's been over engineered to its own detriment. The mounting arm materials did not meet my expectations but just about everything on Amazon is of the same quality. Only my iOttie really had a premium feel and structure. Unfortunately the ball used to mount the phone holder is not the same size as this one. Otherwise I'd just swap them out.*********6/20/19 Update**********Well I've added a star for a couple of reasons. I used silicone glue on the arm and now it holds tight. I also unscrewed the back of the charger and was very easily able to disconnect the right sensor and flip it upside down so it didn't accidentally connect. Closed back up no problem. No real skill or technical savvy required. The seller has stayed in touch along the way and honestly their service was better than Amazon as of late. The ease to fix the issues I had and the sheer willingness of the seller to keep me satisfied warrants another star from me. It's just about perfect after my minor alterations. Good company!I bought 2 of these - one in Feb 2021 and another one in March 2022. I loved the first purchase so much, I bought the second one. I was very happy with the suction on the mount (it was almost impossible to take OFF once it was on!), and the charging speed is excellent. I was able to use this charger with my phone case, which was metal, and my husband could use it with his rugged phone case, which is even bulkier than mine.THREE problems with this unit (2 minor, 1 major).1) If you live in a very hot climate (we live in the southern US), it might take a couple of minutes after you've cooled off the car for it to start charging. Not a big deal. We also had the same problem when it was extremely cold and had to wait until the car warmed up a bit before it would charge. The unit still opened and closed, but the charging wouldn't start until it was cool enough (or warm enough).2) If you have a heavy phone, bouncing around in the vehicle might cause the screw that holds the main unit to the ball joint to loosen and the phone will start to droop. Once it droops too far, the phone will fall out. This might not happen with a lighter phone, or one without a case. It can also cause the screw that is used to telescope the arm to fall off, which is a royal pain to get back on again (you have to take the unit completely off where it's mounted to get the screw lined up with the hole it goes into). Just beware the weight of your phone might cause this problem.3) This one is the major problem - the threads that hold the ball joint to arm of the unit broke off. I suspect it's because of the heat and/or the bouncing around in the car. We both mounted the charger exactly where we wanted and it was only adjusted if we needed to remove the entire unit or if it bounced itself loose, so it's not like we were frequently moving it around or anything. When we would tighten the screw when it came loose (see #2), we only tightened it until it stopped moving, never forcing it any tighter because the threads are made of thin plastic that seems to be cheaply made. The entire rest of the unit is solidly made, but those threads that are permanently attached to the back of the unit are crap. Once these threads break, there is nothing that can be done to fix it.I've sent a message to customer support today, and I will update this review if I receive a response and a satisfactory solution.Alles in allem macht die Halterung ein soliden Eindruck. Leider öffnet sich die Halterung teilweise von alleine und das Smartphone fällt raus. Ich weiß nicht, ob ich da eine Fehlproduktion bekommen habe, aber das sind meine Erfahrungen.Works perfectly - just remember to touch the unlock button before turning car off - would be great if ti could hold on to a charge for 5 to 10 seconds so that the clamp could be used once the car is off. Also be aware that there is no cigarette lighter adaptor included in package, I have several so wasn't an issue for me.I liked this wireless charger, would sometimes open and drop my phone while I was driving, or didn’t always close when I put it in the cradle and drop when you turn a corner. The suction power was no good. The suction part melted off the windscreen within 7 months. I don’t think that’s good enough.2 buttons on the side. Hand always touches the side when using phone and unlocks the phone from its stand/falls.No fast charging on the s21 ultra
